Climate change is one of the most challenging issues for this century, affecting cities and their billions of residents globally. In Southeast Asia, Thailand and Malaysia share similar agricultural based culture and amphibious context. The affects from climate change however, have made us vulnerable to environmental impact such as heavy rain, flooding, rising sea levels, and water pollution. Extensive urban development furthers the effects of climate change by increasing temperatures through the urban heat island effect and limiting appropriate water drainage. Major cities lie at sea level and face especially severe consequences. Bangkok, Thailand; Jakarta, Indonesia; and Penang, Malaysia provide special case studies for Southeast Asian cities dealing with adverse effects of climate change, particularly related to water issues.
